When a child has a fever, parents should first figure out 6 things: 1. What is the fever? Generally speaking, fever can be divided into two cases: one is caused by infection, medically called infectious fever, is a defense response of the body to the invasion of external bacteria, viruses. The other is non-infectious fever, which is not caused by bacteria or viruses, such as rheumatic fever, drug fever, mild fever after vaccination, etc. When a child has a cold or fever, parents should observe carefully. If the child becomes depressed and does not want to eat when the fever rises, but is lively and active once the fever subsides, there is basically nothing wrong. If your child is still depressed, cold hands and feet, or with diarrhea, crying when urinating, etc. after the fever has subsided, you must go to the hospital. 2.Will the fever burn the brain? Some parents worry that a fever will “burn out” their child’s brain. In fact, there is no such thing. The reason why people have this idea is because they see some children because the fever does not go down and “become stupid”, so they mistakenly think that the fever has “burned” the brain. In fact, these children are suffering from encephalitis or other diseases that cause mental decline, and fever is just a manifestation of the disease. Of course, some fevers do have some effect on intelligence, the most typical being febrile convulsions. Some children are particularly sensitive and will “cramp up” at the slightest fever. If repeatedly “cramps”, it will affect the function of brain cells and affect intelligence. 3, the effect of medication is not good immediately change the medicine? Some children do not lose their fever after taking a day’s medication, so parents are anxious to go to the hospital again and insist that the doctor change the medication. In fact, the drug eaten or intramuscular injection, intravenous drip into, to achieve effective blood concentration, it takes a period of time. It is certainly not reasonable to say that the drug is not effective before the time is up. Usually, a drug should be used for at least one course of treatment. If it is still not effective, it is not too late to change the medicine. 4, fever must be sent to a large hospital? For many parents, when their children are sick, even if it is a minor illness, they must go to a big hospital. In all fairness, it is not necessary to go to a big hospital for a cold. Big hospitals may have better equipment and doctors with higher levels of education, but these are not necessary to see a cold. The level of the big hospital is mainly reflected in the handling of difficult cases, community hospital doctors to see the flu and tertiary hospital doctors to see the flu, basically no difference. And the medical environment of big hospitals is not good for children at all, not only the long waiting time in line, but also easy to cross-infection. 5. Is it necessary to test blood for fever? When a child with a fever is seen, the doctor will usually issue a blood test and send the child for a routine blood test. At this time, parents are distressed and feel that blood tests are not necessary. In fact, the results of routine blood tests are very important for doctors to determine the condition of the child, which can indicate whether the fever is caused by viral infection or bacterial infection. 6.Do I need to take an IV or anti-inflammatory medicine? Many parents think that children with fever must be given an IV or anti-inflammatory drugs, otherwise they will not get well. Is it necessary to use anti-inflammatory drugs for a cold? The answer is to use them when you should, but not when you shouldn’t. Antibiotics do not kill viruses, and when a fever is caused by a viral infection, using antibiotics is not only ineffective, but may also cause damage to liver and kidney function, hearing and other aspects, which is not worth the loss. Some parents also prefer to take a drip, thinking that the last time their child had a fever, it would be better to take a drip. In fact, it is necessary to analyze the specific evidence for an IV. If a disease can be oral medication, not to play muscle injection; if you can play muscle injection, not to choose intravenous infusion.
